Original applicatioi'i filed April 17, 1922, Serial No 553,900. Dividedand this application filed August 7 .e, 1924. Serial No. 730,339. I

I This invention is a-division of-inyapplicm tion Serial No. 553,900filed April 17,1922, re-' late-s to the glass art and more especiallytoan automatic blowing machine. I I

Heretofore in the artthe rnost common type of presses-has'been of thestop and start type; that is, the mold table had anintermittentniovenient so-that the whole inass'of metal, comprising an the revolvingparts of the 1nachine, was stopped and started for each piece ofwareinanufactured. This ITIOiZiOIIiIHPOSQCl a very heavy duty upon thedriving 1116Gh' tnism as well as on the press, because of necessitythese very heavy parts had to be started, moved, and stopped at verysmall intervals of time when a. machine was deliveringmany pieces" offinished glassware per minute. This stopping and startins rendered theload Condition on the driving'ihrces very unsatisfactory because at onetime there-was .no leach-as when the press is stationary,-

and at the next instant the loadwas exceedingly heavy. If severalmachines were op-. erating in unison thls load disturbance waspyramided; Since several machines other than presses were usually runfrointhe same driving plant this variable load factor CllS- curbed theoperation-of other machines, unless the operating power was so powerfulas to be iueiiicient and wasteful in operation. lhe jerky notion alsojerked the glass charges around in the'mold andunder certain conchtionsintroduced defects in the ware. Furvertedeither in, one step or the oter. This thermore,'sucha type of machinenaturally re quired constantrepairs-because of loosening of parts'and'breakage. Y Y

It has also been the practice in the art to provide complicatedmechanisms'for transferring the chargefro'rn thepress nold to the blowmold. In many-case's this was done by an inversion met-hod wherethe chare was inwasliable to change the shapeand condition of the glass andproduce idefe'ct's the ware. Various types of split pressm'oldshave-been in use but these molds leave seamsinrthe fini shcd warewhere-the split press mold parts meet. j This is due tcthe verysensitivecharacter of the glass when it leave's. the feeder.

and before a thick skin is formed on the charge. Fur-thern1ore,complextransferring mechanisms increase the weight-of moving parts and.slow'up the; machine.

The machine em VVhere autonia'tic feeders have been used it has been thepractice to drive the feeder independently oi the press. This has madeitnecessary to coordinate two separately driven machines to securearcoinmon-timing forthe interval when the glass is delivered from thefeeder to the press.- There are times when it is necessary to change therate ofthefeederand .there are times when it is desirable to change therate of the press. These changes may be desirable simultaneously, or,either the press or the feeder may require the change. However, in anycase where a change is made in either-the feeder or the press as totherate ofxcharges delivered or the rate of finished ware produced, acorresponding change must be made 1n the other machine; VVliere the two.machineshave independent'drives any I change requires doublemanipulation and ad justments which must properly time the feederandpress at the new rate before Ware can be made.

The 1n achine embodying the inventionhereinazfter specifiedcomprises acontinuously rotating mold tab-1e having a constant speed of rotation,except when the speed is changed for achustments, and whereinthe-feeding, pressing, b-low1ng, and delivering operations are allperformed without in anyway changing the speed of rotation of themachine.

Under these conditions t-he load is-very even and the machine operateswith minimum shock and jars. The power consumed. y I

a constant and efiicient-drive'is the result.

' The charge-transferringdevices areisimple and are so located that thechargejis' not dischine occupies small'floor space; i

tionvmay be generally'described emscomprise "light and since no abnormalload is pr'oduced;

oodying the present invening a base .frame upon WhichaIl't-he;meche;

nisnis except the feeder are moun'tcd :This base frame carries a central'coluninwhichis a mast around which the machine is built.

The niold table revolves around this column andcarries press molds andblow molds. {The press molds rise through the mold tablebetween themembers oiithe split blow-molds and receive the glass charge whichisdropped from the feeder into sf-unllel'th-at at the feeding moment ismoving clockwise with the mold. When the mold is fed the funnel leavesthe mold and moves counterclockwise to a point slightly beyond the pathof the falling charges, where he funnel is positioned over the next moldin the series and the cycle of feeding is repeated when the mold comesunder the feeder. A pressingplunger which travels with the funnel ispositioned over the mold previously charged when the funnel ispositioned over the succeeding mold. Suit able ring molds are broughtinto cooperation with the press mold before the plunger descends. Duringthe pressing operation the plunger and funnel both travel with theirrespective molds. In. the machine there are a plurality of groups ofmold members carried by the mold table and but one funnel and oneplunger to serve these molds. The mold table, therefore, continuouslyrotates while the funnel and plunger oscillates. When the pressingoperation is completed the nekk .of the ware is termed to overhang asplit ring mold and then the plunger rises and the solid block pressingmold descends, leaving the charg e suspended from the neck ring mold.After the descent of the pressing mold a slide brings the bottom of theblow mold into place beneath the charge and a blow mold then closesaround the charge. A. blow head descends npofithe ring mold and air isadmitted to the blow head, thereby blowing the charge into a finishedarticle. The blow head then rises slightly and continues to blow coolair into the blown article, thereby gently cooling: the hot glass. Theblow mold now opens, the bottom slide moves out and carries outwardlythe finished piece of ware. An automatic take-off comprising a pair ofspring operated jaws then grasps the were and removes the ware from theslide by a circular and. at the same time, lifting motion so that theware is elevated slightly as it is removed from the bottom of the blowmold. At the next station the press mold rises and the cycle isrepeated. in the machine herein disclosed there are six mold stations onthe mold table and six cycles performed during one complete rotation ofthe mold table.

Realizing that the present invention may be embodied in constructionsand devices other than those herein described and shown it is desiredthat the disclosure shall he considered as illustrative and not in thelimiting sense.

Main drive and main frame.

In view of the fact that it is desirabld to be able to regulate thespeed of operation of the machine, it is necessary that a variable speeddrive be provided and this is accomplished by means of a variable speedmotor 1 whi h is mounted on the main frame 2 and is connected by shafts4 and 5 together with suitable connecting caring 6 with a control wheel7 so that the fi eld of the motor may be controlled in such manner as toobtain a relatively large range of speed. The particular speed for whichthe motor is set to run is indicated on the dial 8 which faeeslthecontrol handle wheel 50 that an operator manipu' latin the wheel mayobserve the needle on the dial to determine the speed at which-the motoris being set to run.

The motor shaft carries meshes with a gear 10 theta-mounted on the stubshaft 11. A gear 12 on the stub shaft 11 is in engagement with a gear 13on a inion 9 which a front section of the main shaft he stub shaft 11also carries how-l goal l4 which meshes with the hovel pinion if. on thehand driven shaft 16 whivh permits the operator to place crank on the.squared portion 17 and thereby turn he machine in hand when desired. Thehand dria'rn meohauism runs idly when the lllzfllilli. driven by themotor. The front seetion of (l min shaft carries one half of a d sheiuh. l :smiiher 18 and tho main drive shaft 1 as the other half of thodisk ciuiulz. 'lieis. dish ulnteh adapted to he. operated by the lemr 2%which is operated by pinion 21 and on he mmlgrc-l shaft 24 whirh carriesthe main control hand lever 25 so that when this lever is operated thedisk clutch may he opened or dosed to connect or disconnect the mainshaft l9 from the motor drive. Tho main shaft carries a hovel pinion 26which connerts with :1 corresponding pinion 27 on the shaft 528 thatcarries a worm 29 which drives tho w orm wheel 30 that open ates thetakooli mechanism which will be described later.

This head carries planetary gears 54, the larger of which mesheswith the stationary annular gear 55 and the smaller of which meshes withthe annular gear 56 that is attached to the out sido annular gear 57. Apinion 58 is carried by the short shaft 59 mounted in the frame 48, hid!shaft carries another pinion 60 on its outer end. This pinion U0 mesheswith the small pinion of the double reduction gear (31 is oporatod toclose the disk clutch then the' positive clutch 44l5' is opened and thegears 46 and 47 are in mosh. Power from the main shaft 19 is transmittedto the gear 46 and from it to the gear 47, which drives the revolvinghead 52 and causes the planctary gears 110 travel around the stationaryan nular gear 55. This motion causes the planetary gear to transmit aslow speed to the annular gear 56 dependent upon the ratio of truth inthose several gears. Power is then transmitted from the annular gear 57through the gears 58, 59', (if) and 61 to the pinion 62 on the feedershaft 44. This feeder shaft is formod in several sections connectedtogether with pairs of bevel gears and finally is conneeied byuniversal, coupling 64 with a shaft 05 that extends parallel to thetrack of the mach ne. This shaft 65 has a sliding key. drive ongagmuentwith the sprocket Wheel 66 that is set-i red to tho stationary post 67.The i t ('airiCS a silent chain 68 which drives the, ei-atrd by thesliding shaft, permits the rhino to he withdrawn from beneath l'eodurwithout breaking the drive to feeder.

The hlow mold illustrateda split mold formed of members 701 that are pivotally mounted uponremovable pins 702 that are held in place in sockets in ti.- mold tableby lock pins 704. These blow mold members 701 are connected on theoutside portions with the adiustable spring links 7,5 which are slidahlethrough posts 706 on the slide plate 707. This slide plate carries aroller 708 that travels in the groove 709 in the stationary earn 710when the mold table rotates around the colun 35. The operation of thisslide causes the inks 7 05 to positively open the mold and permits thesprin s on the links to yieldingly close the mold. he bot tom of theblow mold 701 com rises a base or button 711 carried upon a sli e 712that is mounted upon the mold table 101. The slide carries on its innerendan actuating roller 714 that travels in the groove 715 in thestationary cam 716 when the mold table revolves. This slide, (Fig. 15)is provided with an opening 717 through which the press mold 109 riseswhen the slide 712 is in. outer position, which is the position of thismember in all but two stations in the operation of the machine. Thisslide 712 is also provided with a slot 718 which provides clearance forthe pin 7 02 that forms the pivot for the blow mold sections.

In order to hold the blow mold securely locked a cam operated loel: isprovided on the outer portion of the mold table. This lock isillustrated more specially in, Figures and 2. It comprises a baseportion 710 which slides in guides 720 and carries a roller 721 thattravels upon the circular cam that mncentric with the block mold tracklit". The base member 7l9 is telescopically connected with a carrier72-1 that is maintained in extended position by a coiled spring 725.This carrier carries a locking head 726 that is mounted upon rollerbearings 727 to provide lateral movement during' the locking operation.llat'll mold member 701 is provided with an extension 728 that isprovided with a (lt'nvmrardly inclined tare so that when the lo l in;head 726 is raised it wedges thew membcrs together and tightly locks themold members in closed relation.

When the blow mold 701 is closed the blowing operation commences and thedevi es ior this operation are illustrated more particularly in Figures2. 7, 10, 11, 12, it; and The blow head L adapted to lit tightly againstthe upper surface of the solid ring mold and is carried upon a. pair ofswinging arns 802 which are pivoted to rotate on the ring mold frame.The blow head carries a spriing, F 01 that compressed when the arms dcf'tl'hl after the hlow head contacts a ith the ring mold. The m it. 805upon which the arms R03 are mounted carries a gear 9106 which mesheswith the slid-able rack 807 that also mounted upon the rme mold frame.This rack carries a roller out; which the spring 803 holds against thestationary cam 809 that is mounted upon the column 35. The cam 809 5'provided with an adjustable part 810 which permits the time of opcrwtion of this cum to be shortened or lea ill ened at will.
